Application filed April 16, 1909. Serial No. 490,290.

To all whom it may concern:

lie it known that we, Fonnns'r HILL and Yunnan E. HILL, citizens of theUnited States, residing at Emporia, in the county of Lyon and State ofKansas, have invented a new and useful Improvement in \Vagon- Loadersand Graders, of which the following is a specification.

This invention relates to certain new and useful improvements in wagonloaders and graders, the object being to provide a machine which is soconstructed that it can be easily and quickly operated and one which isexceedingly simple and cheap in construction, the parts being soarranged and connected that they are not likely to get out of order inuse.

Another object of the invention is to provide automatic means foroperating the scoop whereby it can be raised with its load so that thesame can be dumped into a wagon.

A still further object of the invention is to provide novel means forraising the scoop whereby a positive movement will be imparted to thesame by the operation of a lever.

A still further object of the invention .is to provide a machine whichis mounted on wheels having a clutch mechanism mounted on a drive axlefor operating a drum which carries a. cable for operating the hoistingframe.

A still further object of the .invention is to provide the main axle ofthe machine with driving wheels having ratchet hubs which are adapted tobe engaged by pawls carried by fixed members whereby the axle will berotated on the forward movement of the machine.

Another object of the invention is to provide a frictional brake inconnection with the winding drum whereby the hoisting frame carrying thescoop can be lowered after the load has been dumped out of the samesmoothly.

A still further object of the intention is to provide a pivoted scoopwhich is so constructed that when in a lowered position it will be heldfirmly when the same is driven into the ground as the machine is movedforwardly and it will also be held firmly with-- out any danger of itmoving in any Way.

A still further object of the invention is to provide novel means fordumping the scoop when in a raised position.

A still further object of the invention is to provide automatic meansfor throwing the clutch so as to stop the winding of the drum when thescoop has reached its uppermost position.

WVith these objects in View, the invention consists of the novelfeatures of construction, combination and arrangement of partshereinafter described, pointed out in the claims and shown in theaccompanying drawings, in which,

Figure 1 is a side elevation of our improved machine partly in section.Fig. 2 is a top plan view of the same. Fig. 3 is a vertical sectionthrough the hub of the wheel and pawl carrying ca p, the rim beingpartly shown in elevation. Fig. 4. is an inside view of the pawlcarrying cap. Fig. 5 is an elovation of the wheel with the pawl carryingcap removed and Fig. 6 is a detail view showing a modified form of meansfor raising the hoisting frame by hand.

In carrying out our improved invention we employ a tri-angular frame Aprovided with a drive axle B at one end having driving wheels C looselymounted thereon which are provided with internally toothed hub portionsC adapted to be engaged by spring actuated pawls D carried by caps l!)which fit within the hub portions of the wheels and are secured to theaxle so that they will rotate with the same whereby the axle will berotated as the machine is moved forwardly. The other end of thetri-angular frame is supported by a c: ster wheel F and is also providedwith a double tree G to which a pair of horses are adapted to beconnected. The drive axle carries hold-backs G at its outer ends and itwill be seen that by this arrangement the machine can be moved forwardlyby a pair of horses so that the scoop which is arranged at the front ofthe machine will be in advance of the horses as will be hereinafterfully described.

Secured on the side members of the triangular frame A are standards IIwhich are provided with braces It" so that the same will be held in arigid position thereon without any danger of them moving.

A shaft H is mounted in the upper ends of the standards ll on which ispivotally mounted a substantially pyramidal hoisting frame J carryinghangers J which are pivotally connected to clips K secured to the sidesof a scoop K which has runners K scoured on its bottom which extend outto the rear and are connected to the back of the scoop by braces Kadapted to strike the axle when in a lowered position so as to hold thescoop firmly whereby all danger of it twisting is prevented when thesame is forced into a pile of dirt. This hoisting frame is so mountedthat it swings freely on the shaft, whereby it can be swung upwardly soas to raise the scoop in position as shown whereby it can be dumped intoa wagon. For operating the scoop we employ a crank L which is carried bya sleeve L mounted on the shaft H between the standards H, said crankbeing connected to the sleeve by braces and having an operating rod Lpivotally carried by its free end which extends forwardly and is securedin a T-coupling K pivotally mounted on the bail K of the scoop K wherebythe scoop can be swung on its pivot so as to dump a load by forcing theoperating rod forwardly which is accomplished by a lever L connected tothe lower end of the crank L and connected thereto by a suitable brace,said lever extending rearwardly .over a platform A secured on the frameA adjacent to a seat A mounted thereon so that the operator can dump thescoop by simply pulling upwardly on the lever.

Mounted loosely on the axle B is a winding drum M which is provided witha ratchet wheel M carrying a toothed clutch member M adapted to beengaged by a coacting clutch member M which is slidably mounted on theaxle and is keyed thereto, said clutch member l 3 being normally heldinto en gagement with the clutch member M by a coil spring ,l 4 wherebythe drum will be revolved when the wheels are rotated. For operating theclutch member M we employ a pivoted crank N which is connected to theclutch member 1V 3 by a yoke in the ordinary manner and has an operatingrod N connected to its outer end which extends back and is connected toa foot operated lever i 3 arranged adjacent the seat whereby the clutchmechanism can be thrown into and out of engagement for operating thesame it of course being understood that the spring M only holds theclutch members into engagement after once being thrown.

Mounted on the drum M is a cable 0 which passes through a snatch block 0carried by the pyramidal frame J and has its free end connected to themain cross bar of the frame whereby the frame will be swung forwardlyand upwardly when the cable is operated so to raise the scoop after ithas been loaded and secured on the cable is a clip 0 adapted to engagethe snatch block so that at the last movement of the hoisting frame adirect pull will be obtained and it will be seen that by thisarrangement when the frame with its load is first started the power isincreased by the pulley until the clip carried thereby is brought intoengagement with the block and then a direct pull is obtained so that theload will be raised faster. By this arrangement the sudden strain of'starting the frame carrying the loaded scoop is prevented whichincreases the life of the machine and prevents any of the parts beingbroken by sudden jerking which would be the case if a direct pull wasobtained at the start.

In order that the upper movement of the hoisting frame may be stopped atthe correct time we employ a crank P which has one of its arms connectedto the operating rod N and the other arm to the hoisting frame by a rodP which is provided with a turn buckle so as to take up lost motion andit will be seen that when the hoisting frame reaches the desiredposition the crank is operated which in turn operates the crank Nthrough the medium of the rod N which draws the clutch member M out ofengagement with the clutch member M so as to stop the winding of thedrum.

For preventing the drum from unwinding after the cable has been woundthereon we employ a pivoted pawl Q which is adapted to engage theratchet M carried by the drum said pawl being operated by a crank Q towhich a coil spring Q is connected and to which an operating rod R isconnected which extends rearwardly and is connected to a foot lever Bmounted adjacent the seat so that it can be easily operated in order tothrow the pawl out of engagement with the ratchet when it is desired tolower the scoop after it has been dumped.

For regulating the speed of the drum we employ a frictional brake whichcomprises a drum S carried by the drum M and having a band S passingover the same, one end of which is connected to the cross beam of theframe A and the other to a crank S to which is connected an operatingrod S which extends rearwardly and is connected to a pivoted lever Tmounted adjacent the seat to which is connected a coil spring T which isof sufficient strength to hold the band taut over the frictional drum inorder that the speed of the same will be regulated but if desired thelever can be grasped by the hand and the tension increased so as todecrease the speed of the drum which in turn decreases the descent ofthe hoisting frame. It will be seen that by this arrangement thehoisting frame can be lowered smoothly without any danger of allowingthe same to drop with a jerk which would probably break the same as thespring will apply a sufiicient tension to the frictional brake to lintinstead of employing the clutch mechanism as heretofore alreadydescribed for operating the drum through the medium of the wheels weemploy a ratchet V and a lever \V carrying a spring actuated pawl \Vwhich is operated by a triangular shaped block X through the medium of arod X and a lever X, and it will be seen that by working the lever Xback ardly and forwardly the drum will be rotated so as to wind thecable Y and hoist the frame Y.

From the foregoing description it will be seen that we have provided amachine which is provided with means for automatically raising the scoopafter it has been filled and by operating a lever the load within thesame can be readily dumped into a vagon but it is of course understoodthat this luaehine can be used with great advantages for carrying theload after it has been raised when the distance is very short therebysav ing a great deal of time and expense.
